\ Be it known that I, Li'ioN ABEL CELEB. LE'roMBE,a citizen of the Republic of France, residing at Paris, France, have invented Imrovements in Apparatus for Automatically tarting EX losiv'e-Moto'rs or the Like, of which the following is a specification. I

Thepresent invention relates to a comfluid distributingdevice employed in connection with means for automatically starting explosion motor'sor the like and,

com inations of elements hereinafter fully tact with the casing end its cylindrical extension forms a dash pot on which only communicates with the atmosphere through a-smallhole 11. The motor starts immediately the valve, driven by the general movement of'the engine, turns while remaining held in contact with the casing end by the pressure of the compressed ases which are thus distributed inturn to al the .cylinders during their working strokes.
